In this post, it is shown how to design a BJT amplifier with voltage divider on common emitter mode. Two examples of projects are presented.
In this post, are shown 2 circuit projects: an AC voltage detector and a cooler with LED effect.
The current sources are electronic circuits that provide a constant current. In this post, are shown some examples.
This is the post’s second edition. It’s shown one more project to control servomotors with a joystick, using another method.
This is a project of a vehicle with tracks controlled by a pair of RF modules and intergated circuits HT-12E (encoder) and HT-12D (decoder).
It is possible to control a robotic arm without a microcontroller, using simple electronic circuits. This post shows how.
The Seebeck and Peltier effects are thermoelectric phenomena that explain the operation of thermocouples, temperature sensors with 2 different materials.
In addition to parallel and series, impedances also can make star and delta connections. Also are shown the transformations.
This is the third and last part of the series about BJT transistor polarization. Other circuit configurations are shown.
I received requests to write more about capacitance and inductance. This post can be considered as the second part of derivated electrical quantities.
